The alligator gar is the largest species of gar and the largest fish, overall, in the Mississippi River Valley. It is also one of the largest freshwater fish species in North America. Gar are widely believed by researchers to have a maximum size exceeding 300 pounds, but only smaller fish have ever been measured.
The largest confirmed alligator gar was caught in 1951 by Bill Valverde in the Rio Grande. Anecdotal reports exist of a 350-pound alligator gar caught in the 1930s in the St. Francis River, Arkansas; however, Arkansas fishery records list the largest gar caught in the state as a 215-pound fish caught in 1964 by Alvin Bonds.Learn more about Fish
